OK, so the MC was in the hero's party, a healer, and a friend of the hero. She was weak, got sick a lot, and depended on the hero to encourage and keep her living, and she herself knew those facts. Some time after, one of her comrades invited her over to "scout", which she accepted. Her comrade asks her if she'll be useful in the party, to which she replies, "I think if you get hurt I'll do my part." He refutes that by telling her that nobody in the party would get hurt enough to need her. She doesn't reply to what he says, so tells her and shows her that she's not needed in the party, showing her recordings of the hero saying that someone like her isn't needed. And that's when he tries to kill her.

She falls down into an abyss, her legs (and body, in general,) twisted in the wrong direction, barely maintaining consciousness with the feelings of betrayal and guilt lingering in her mind, and that's when she hears a voice containing emotions similar to hers. With some events that I'm not going to mention, she finally gains the power she wants. Then it just ends.

Like come on, that plot is preetty interesting. I'm not satisfied with the story ending, otherwise it was great.
